Non-ramped .38Super barrel

I've been working on one and the rounds hang on chambering. Found that the ramp on non-ramped barrel extends too close to the frame ramp (doesn't have the 1/32" leeway). Is it better to contour the barrel (I am concerened about cutting it too short for shell casing support if I contour the barrel), or to "build up" the frame ramp?

If it were me, I'd file back the bottom edge of the barrel, and recontour the throat to a "steeper" angle. Don't cut back the bottom edge of the chamber (i.e. top of the barrel ramp), just work on the lower part of the barrel's ramp.

Really I think it depends on just how the frame ramp was cut. If the frame ramp was cut with a shallow angle like a 45 ACP, you may be out of luck. If that is the case there are two solutions. Have a steel ramp insert installed in the frame, then recut the ramp or have the frame cut for a ramped barrel.

Now if the frame ramp is cut to a steep angle and the barrel chamber has not been altered and has more support than necessary, then you can modify the barrel ramp. I do agree that cutting the barrel ramp at an angle that does not lessen case head support should be attempted first. You may still end up with a gun that will only feed round nose bullets.

A third possibility is that the barrel has a long link and is being positioned too far to the rear or the back side of the lower lugs have been cut and the barrel is allowed to move back too far or possibly the frame was cut in this manner. If the barrel or frame are out of spec, you may need a new, fully fitted barrel to correct the problem.

Thanks Gentlemen! The complete setup is "aftermarket" with no "known" name parts. The frame could be orginally designed for the .45ACP (it works great with 45 slide & barrel).

If the barrel link were too long, wouldn't that affect lock-up also? Would I really want the link (alone) to accept all the pressure of recoil and not have the lower barrel lugs contact the frame?

Again, Thanks

A long link can seriously affect the link down of the barrel. Barrel links down too late and the slide just hammers the radial locking lugs. Using a bunch of unknown parts makes it really difficult to diagnose and fix.

And no, lock up on the link is a bad thing too, it's not that stable and wears out quickly. Yes, I speak from my own experience.

Played around and got it to feed a complete mag without a hitch (so far). Now to get out and shoot the thing.

Thanks for the assistance. (You guys are great!)
